Turbo Chef Technologies NGC-1007 F1 Blower Running Status Bad, F2 Cook Temperature Low

Page 20

The NGC (Tornado) oven has the ability to continually monitor and log various fault conditions. Some fault conditions will terminate cook cycles, while others will not. Please refer to the fault code table on page 12 for more detailed information.

When a fault is detected, the Fault Log will incre- ment. However, if the fault is subsequently cleared by some action, whether service related or not, the Fault Log will not decrement.

TO VIEW FAULT CODES

To view the Fault Log, simultaneously press the “4” and “6” keys while the oven is in the OFF STATE. The oven will display all faults logged. Figure 6.

Each fault will log up 255 instances before rolling back to zero. To zero the log, see pages 14-15

(TEST MODE).

N O T E : The Fault Log also displays cook counts, which will log up to 65,535 cook cycles. In order for the control to log a cook cycle, the oven must complete the first event of any given recipe. If a recipe has only one event, the oven must complete the entire cook cycle in order to count it.

FAULT CODE DEFINITIONS

F1: Blower Running Status Bad

Fault is displayed when the motor controller indicates no running status.

The motor and motor controller are monitored con- tinuously in all modes with special handling in SELF TEST and TEST MODE. If a fault is detected, the con- trol will terminate a cook cycle and display F1:

BLOWER. Upon turning on the oven, the control will attempt to restart the motor. If the restart is suc- cessful, the fault code will be cleared. The fault is also cleared from the display at the onset of cooking or when the blower motor is tested in TEST MODE.

F I G U R E 6: Fault Log

F2: Cook Temperature Low

Fault is displayed if the cook cavity temperature is more than 84ºF (47ºC) below the set temperature after five (5) seconds into a cook cycle.

The fault is cleared from the display at the onset of cooking if the cook cavity temperature is within 84ºF (47ºC) of the set temperature or when the heater is tested in the TEST MODE.

F3: Magnetron Current Low

Fault is displayed when the current transformer (CT) on the I/O control board does not detect enough current. The fault is monitored when the microwave is on during a cook cycle or self-test.

The fault is cleared from the display at the onset of a cook cycle if the CT detects current or when the magnetron is successfully energized in TEST MODE.

F4: Door Monitor Defective

Fault is displayed when the control detects that the monitor interlock switch unlatches before the pri- mary or secondary interlock switches.

In addition, this fault will blow the F3 fuse if the microwave high voltage system is energized when the fault occurs. The fault is cleared from the display when the oven is powered off and then back on.
